This is the ansible yml, I run it on an ansible control node to apply flannel network of the master node. And I am a root user.
- name: Apply flannel network
shell: sudo kubectl apply -f /tmp/.ansible/files/kube-flannel.ymlAnd the ansible give me this error:
"unable to recognize \"/tmp/.ansible/files/kube-flannel.yml\": Get http://localhost:8080/api?timeout=32s: dial tcp [::1]:8080: connect: connection refused"]}But,when I manually login the master node and run sudo kubectl apply -f /tmp/.ansible/files/kube-flannel.yml it works without error.

I have add the following cmd in the ansible yml, then the pod has been applied successfully. Cause the ansible access master node with an new ssh session, the enviroment value has been discarded.
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/configJust use KUBECONFIG as env variable as below:
- name: Apply flannel
shell: |
kubectl apply -f /home/ubuntu/kube-flannel.yml
environment:
KUBECONFIG: /home/ubuntu/.kube/config
when: inventory_hostname == "kube-master"
